114 This section describes the simple maintenance procedures you should follow to clean the filters, the lens, the cabinet, and to replace the lamp and the filters. 1 Cleaning the Filters The air-filter sponge keeps dust and dirt from getting inside the projector and should be frequently cleaned. If the filter is dirty or clogged, your projector may overheat. NOTE: The message for filter cleaning will be displayed for one minute after the projector is turned on or off. When the message is displayed, clean the filters. The time to clean the filters is set to [6000 H] at time of shipment on M311X/M271X/M271W; the time to clean the filters is set to [5000 H] at time of shipment on M361X/M311W. To cancel the message, press any button on the projector cabinet or the remote control. The two-layer filter on the projector improves cooling and dust-proof capabilities compared with the conventional models. The outsides (intake side) of the first and second layer filters remove dust. To clean the filter, detach the filter unit and the filter cover. CAUTION • Before cleaning the filters, turn off the projector, disconnect the power cord and then allow the cabinet to cool. Failure to do so can result in electric shock or burn injuries. 1. Push the button to release the filter unit and pull it out. TIP: The following explanation uses filters (fine-texture sponge and coarse-texture sponge) attached to the projector at the time of purchase as an example. After replacing with filters included in the optional lamp, replace the words “fine-texture sponge and coarse-texture sponge” with “ac- cordion soft and honeycomb hard” respectively. 2. Remove the filter cover. The filter cover is fixed at six separate mounting points. Bow the filter cover by pushing the notch slightly until it re- leases. 3. Remove the four filters and use a vacuum cleaner to vacuum all the dust inside. Get rid of dust in the sponge filter NOTE: • Whenever you vacuum the filter, use the soft brush attachment to vacuum. This is to avoid damage to the filter. • Do not wash the filter with water. Doing so can result in filter clog- ging.

116 7. Maintenance Cleaning the Lens • Turn off the projector before cleaning. • The projector has a plastic lens. Use a commercially available plastic lens cleaner. • Do not scratch or mar the lens surface as a plastic lens is easily scratched. • Never use alcohol or glass lens cleaner as doing so will cause damage to the plastic lens surface. Cleaning the Cabinet Turn off the projector, and unplug the projector before cleaning. • Use a dry soft cloth to wipe dust off the cabinet. If heavily soiled, use a mild detergent. • Never use strong detergents or solvents such as alcohol or thinner. • When cleaning the vents or the speaker using a vacuum cleaner, do not force the brush of the vacuum cleaner into the slits of the cabinet. Vacuum the dust off the vents. • Clogged vents may cause a rise in the internal temperature of the projector, resulting in malfunction. • Do not scratch or hit the cabinet with your fingers or any hard objects • Contact your dealer for cleaning the inside of the projector. NOTE: Do not apply volatile agent such as insecticide on the cabinet, the lens, or the screen. Do not leave a rubber or vinyl product in prolonged contact with it. Otherwise the surface finish will be deteriorated or the coating may be stripped off.
117 7. Maintenance Replacing the Lamp and the Filters When the lamp reaches the end of its life, the LAMP indicator in the cabinet will blink red and the message “THE LAMP HAS REACHED THE END OF ITS USABLE LIFE. PLEASE REPLACE THE LAMP AND FILTER.” will appear (*). Even though the lamp may still be working, replace the lamp to maintain the optimal projector performance. After replacing the lamp, be sure to clear the lamp hour meter. (→ page 99) CAUTION • DO NOT TOUCH THE LAMP immediately after it has been used. It will be extremely hot. Turn the projector off and then disconnect the power cord. Allow at least one hour for the lamp to cool before handling. • Use the specified lamp for safety and performance. To order the replacement lamp, specify your lamp type. Replacement lamp: NP15LP: M311X/M271X/M271W NP16LP: M361X/M311W The replacement lamp comes with filters. While the filters attached to the projector at the time of purchase are made of dark sponge material, the filters included with the optional lamp are made of non-woven white material. There is no difference in performance between these two types. • DO NOT REMOVE ANY SCREWS except one lamp cover screw and two lamp housing screws. You could receive an electric shock. • Do not break the glass on the lamp housing. Keep finger prints off the glass surface on the lamp housing. Leaving finger prints on the glass surface might cause an unwanted shadow and poor picture quality. • The projector will turn off and go into standby mode when you continue to use the projector for another 100 hours after the lamp has reached the end of its life. If this happens, be sure to replace the lamp. If you continue to use the lamp after the lamp reaches the end of its life, the lamp bulb may shatter, and pieces of glass may be scattered in the lamp case. Do not touch them as the pieces of glass may cause injury. If this happens, contact your NEC dealer for lamp replacement. *NOTE: This message will be displayed under the following conditions: • for one minute after the projector has been powered on • when the (POWER) button on the projector cabinet or the POWER OFF button on the remote control is pressed To turn off the message, press any button on the projector cabinet or the remote control.
